OPERATION 237
Safety Information Mack utilizes the use of a Diesel Particulate Filter (DPF) and Selective Catalytic Reduction (SCR) to meet EPA2010 emissions. The system is designed to require very little driver interface to maintain correct operation. The technology utilizes a passive regeneration; requiring no fuel to be injected to clean the DPF. In EPA2007 an active regeneration (fuel was injected) was required to clean out the DPF producing very high exhaust outlet temperatures. Certain vocational duty cycles will require the use of fuel and/or a parked regeneration to clean out built-up soot in the particulate filter. Exhaust temperatures will increase during a parked regeneration. When parking the vehicle to perform a parked regeneration keep away from any flammable materials, vapors or structures.
DANGER Exhaust gases and components can be at extremely high temperatures during regeneration. When parking the vehicle, keep away from any flammable materials, vapors, or structures.
DANGER The temperature of the exhaust system components during the regeneration process can exceed 350 degrees C (660 F). The exhaust gas leaving the system can reach 505 degrees C (930 F). Various factors (including ambient temperature and duration of the regeneration process) determine when these components will return to normal operating temperature after regeneration has completed. Be extremely careful around these hot components. Contact with these components can result in serious personal injury.
